CONTINUOUS ROLLING-MILL.

SPECIFICATION forming part of Letters Patent No. 277,044, dated May 8,1883. Application tiled December 23, 1882. (No model.)

tinuous Rolling-Mill, of which the following isV a specification,reference being had to the accompanying drawings.

This invention relates to rolling-mills; and its object is to provide animproved arrangement of a continuous set or train ot' rolls by which thebillet may pass from set to set through the entire train withouthandling, thereby et'- fectiug a great saving of labor.

My invention consists in the improved construction and arrangement ofparts by which this object is accomplished, as will be hereinafter morefully described, and particularlyv pointed out in the claims.

In the drawings hereto annexed, Figure l is a plan view of a completecontinuous train of rolls equipped with my improvements. Fig. 2 is avertical sectional view on the line x a' in Fig. l. Fig. 3 is aperspective View ofthe open conductor detached. Fig. et is a perspectiveview of the same equipped with the deliveringtube, and Fig. 5 is aperspective view of the flanged billet-table detached.

The same letters refer to the same parts in all the figures.

Continuous rolling mills have heretofore been constructed in whichseveral sets of rolls have been placed in front of cach other withanyconvenientform of gearing. It has always been customary, however, toplace these sets of rolls very close to each other, and the overfeed orsurplus which occurs between two such sets of rolls, and which is due tothe rapid reduction of a billet or piece ot' metal in two I operation ofwhich I shall now proceed more fully to describe with reference to thedrawings hereto annexed, in which- A A represent the sets of rolls ofthe continuous train, and B B represent those ot' an ordinary repeatingtrain which is placed at right angles to and which operates inconjunction with the continuous train A. The rolls ot' the latter arearranged in the usual manner parallel to each other, the several setsbeing placed in front of one another. The axes of the rolls oftherepeating-train are arranged in a line with each other, the entire trainbeing, as stated, at right angles to the train A. The

are preferably locatediive feet or more apart, as occasion may require,so as to atford'space between the sets for an open conductor, trough, orguide, (denoted in the drawings byletter C.) This conductor, asitmayproperly be termed, consists simply of a suitably-constructed opentrough or guttershaped box provided on its vent the billet fromescapingin this direction. E is a large iiat table placed adjoining theuntlanged outer side of the conductor C for the purpose of receiving andsupporting the overfeed of the billet, as will be presently more fullydescribed. Thedelivering end o'i' the conductor is contracted, as shown,and provided vwith a funnel-shaped delivering-tube, F, for the purposeof entering the billet properly into the receiving-guide G of the nextset of rolls. Each set of rolls is also provided with a de liveringbillet-guide, H, so constructed as to be capable ot' delivering thebillet properly edged, as the oval and square passes may require. Theconstruction of this deliveringguide, however, is not claimed herein, asit has already been made t-he subject of a separate application by mefor Letters Patent.

Motion is 'communicated to the rolls of the train A from thelongitudinal main shaft I by means of bevel-wheels J upon the latter.Said main shaft has a keyseat, K, extending over its entire length, sothat the bevel-wheels J may be readily adjusted at any desired place.The rolls A are by preference arranged in three high housings, L, thelower bearings of which are occupied by counter-shafts M, havingbevelsets of rolls constituting the continuous train inner side with aange, D, in order to pre- Y wheels N, engaging those upon the mainshaft. By this construction I avoid the necessity of securing thebevel-wheels upon the necks of the rolls, motion to which iscommunicated by means of ordinary gear-wheels, O. The housings L are tobe arranged or mounted upon a suitable longitudinal bed-plate, P,parallel to the main shaft, and provided, if desired, withsuitableguide-flanges,Q. Bythisarrangement, ywhen a short billet is tobe worked, the housings or sets of rolls may be moved as closelytogether as may be desired or necessary in order to properly work thebillet. The bevelwheels J, being adjustable upon the main shaft, asdescribed, may be readily moved so as to conform to such adjustment.

The troughs or conductors and the ilan ged tables are provided on theirunder sides with vertically-slotted brackets R, by which they arevertically adjustable in the feet or standards S, of which two or moremay be used under each of the said conductors and tables. I also preferto make each of the said ,conductors and tables in two pieces, oneoverlapping the other, as shown in the drawings, in order that they maybe expanded or contracted, so as to correspond with the space betweenthe sets of rolls.

In the construction and arrangement of' the rolls of the repeating trainno novelty is herein claimed. They are to be equipped with the automaticrepeating mechanism patented to myself on the 23d day of October, 1877,so as to be capable of passing a billet from one end of the train to theother without the aid or attendance otherwise necessary. The first passor set of rolls ofthe train B is to be equipped with a receivingguide,G, of suitable construction to receive the billet from the last set ofrolls in the train A.

I would have it understood that although I have described the repeatingtrain B as being arranged at right angles to the train A, thisparticular position is not necessary or essential to the successfuloperation of the device. The two trains or sets of rolls may be placedin any desired position in relation to each other to form a continuoustrain. v

The operation and advantages of my invention will be readily understoodfrom the foregoing description, taken in connection with the drawingshereto annexed. The billet, as it passes from each set of rolls in thetrain A, is conveyed by the conductor G to the next set. Any overfeed orsurplus occurring between the different sets of rolls is allowed tovescape out upon the ianged table E, where it rests during operation.The flange D upon the outer side of the conducting-trough prevents theoverfeed from escaping in the wrong direction. By having the differentsets of rolls should not so much exceed that of the preceding set as tostretch or separate the billet. My improvement, in fact, would worksuccessfully if uniform speed and diameter of the rolls were employedbut as it is necessary to gear each set of rolls separately, it would beadvantageous toprovide for part of the overfeed in the gearing, allowingthe difference to escape out upon the flanged table.

The main driving-shaft of the continuous train A may be propelled in anyconvenient manner'by power supplied by the engine running the repeatingtrain, or by an en gine erected specially for. the purpose. It isdesigned, however, where mills have the ordinary train and .suiicientpower in the engine driving it, to add the rolls constituting thecontinuous train, which may be done at comparatively small expense, thusdoing away with the roughers and getting the full advantages of acontinuous and labor-saving train without much outlay, the engine,ordinary train, and other equipments of the plant being already on theground; or the continuous section can be used alone, if desirable.

I claim as my invention and desire to secure by Letters Patent of theUnited States-el.
